, BOILER-CASING.

Application filed September 3, 1913.

'.`casings or coverings for boilers and has particular application to a portable boiler casing.

Infcarrying out the present invention, it -is my purpose to provide a boiler casing which may be readily assembled to incase the boiler and conveniently knocked down to facilitate packing and transporta-tion thereof. It is also my purpose to provide a boiler casing or covering which will embody in its construction a number of sections designed tobe arranged edge to edge when assembled and each composed of a pair of plates spaced apart in parallelism, and a filler of heat insulating material interposed between the plates, each section having an open edge and a closed edge, the closed edge being designed to abut `he open edge of an adjacent section so that the filler contained in each section will act `to effectively seal the joint between the sections thereby preventing the escape of heat .from the boiler.

Furthermore, I aim to provide la boiler covering of the class described' which =will embrace the desired features of simplicity,`

eliciency, durability and strength coupled with cheapness of cost in manufacture, man -keting and installation and which may bc readily assembled 'and' knocked down.

With the above and other objects in view,

'the invention consists in the construction,

combination and arrangement of parts hercinafter set forth in and falling within the scope of the claim. A

Referring new to the accompanying drawings in detail, A designates a suitable base or foundation composed of any suit. able material suoli, for instance, as brick, while B indicates a steain boiled seated upon the foundation A and adapted to receive heat nfrom a suitable furnace My improved boiler covering or casing comprises a plurality of sections l disposed at opposite sides of the boiler and arranged in edge to edge contact, and an end section 2 cooperating with the front Wall of the furnace of the boiler to close the casing formed by the sections l. rJ'Cliese sections l rest upon the foundation A and have the upper ends thereof curved inwardly so as to incase the boiler shell, the `confronting ends of the sections at the opposite sides of the boiler abutting each other. ln the present instance, each side section 1 comprises a pair of plates 3, 3 spaced apart in parallelism to forni 'a holq low section having the top, bottoni. and one and abutsvtlie closed edge ot' the adjacent section. 'l'hese plates may be riveted, bolted or otherwise secured in section forma# tion and eachhas the upper end thereof formed with an upstanding flange 5 designed to abut the iange on the upper edge of the section at the opposite side ofthe boiler, the contacting flanges being formed with alining apertures to receive bolts f5 or the like. rlhc closed edge ol cach section has 'formed at the inner side thereof a flange 7 coex'tensive in height with the height of the section and underlyingy the inner plate of the adjacent section at the open end foiE the latter' section, while a filler 8 of asbestos or other lieatinsulating material lls the space between the plates of each section, and at the open edge of the same contacts with the closed end of the adjacent section and coperates with,` the iange 7 on suoli adjacent section to seal the casing at the joint whereby the escape of beat, dust and the like from the boiler is obviated.

The end section 2 is constructed in l h a mariner identical to the sections l. hereinbefore The' iront Wall of the boilenurnace may he constructed in a manner similar to the end Wall 2. oi the casing, or ma' be o' any other preferred construction. n the formy oit my invention herein shown, the end Wall 2 of the -casing is seated upon one end of f the foundation A and fastened. in position by means of tie rods 13. lt will be understood, however, that other suitable means may be employed to hold the end sections in proper position.

"ln Fig. 3 of the drawings, l have shownl my improved casing or'coverin'g as applie to a hot air furnace for heating dwelling houses and the like and in this 'case the casing formed by the sections is spaced apart from the Wall of the fire pot of theI furnace so as to form an air space 14 into vwhich cold air may be delivered and from which such air may be subsequently taken `in a heated condition.

From the foregoing description taken in' connection with the accompanying drawings, the construction, and manner of en1-' ploying my invention will be readily apparent.

it will be seen that l have provided a casing or covering for the boilers of hot 'air furnaces and the like by means orwhich maken. win t@ @eiland me which myrte readily assembled and disassembled,

While .l have herein shown anddescribed f one preferred form of my invention by way of illustration, I desire it ton be understood that I do not limit'myself to the precise details of construction herein delineated, as modification andy variation A boiler casing comprising a plurality of sections arranged at the opposite sides of.

the boiler and disposed in edge to edge contact, each section comprising a pair of plates spaced apart in parallelism, and a filler of heat insulating material interposed between said plates, each section having an open edge and aclosed edge, the closed edge ofeach described and section abutting the open edge of the adjacent section, flanges upstanding from the IRA MAR'TiN Horn.
